• If unusual noise can be heard during operation, consult the dealer.

• Symbols which appear frequently in the text have the following meaning:

Observe instructions
with great care

Strictly prohibited Provide proper earthing

WARNING

• I nstallatio n must be carried o ut by the qualified installer.

If you install the sys tem by yourself, it may cause ser ious trouble su ch as
water le aks, ele ctric sho cks, fire and per sonal in jury, as a result of a system
malfunct ion.

• I nstall the system i n full acc ordance w ith the in struction manual.

Incorrec t installat ion may cau se bursts, personal in jury, wate r leaks, el ectric
shocks an d fire.

• B e sure to use only for househ old and r esidence.

If t his applian ce is inst alled in inferio r env ironment such as mach ine s hop
and etc. , it can c ause malf unction.

•

Use the orig inal accesso ries and the sp ecified com ponents for in stallation.

If parts o ther than t hose presc ribed by us are used, I t may cause water leak s,
electric shocks, f ire and pe rsonal injury.

• I nstall the unit in a location with goo d support.

Unsuitab le installat ion locatio ns can cause th e unit to fall and cause mate rial
damage a nd persona l injury.

• E nsure th e unit is stable w hen installed, so t hat it can withstand earth­quakes a nd strong winds.

Unsuitab le installat ion locatio ns can cause th e unit to fall and cause mate rial
damage a nd persona l injury.

• V entilate the worki ng area well in the even t of ref rigerant leakage d ur­ing insta llation.

If the re frigerant comes into contact with nak ed flames, poisonous gas is
produced .

• W hen install ing in smal l rooms, ta ke preventi on measure s not to exc eed
the dens ity limit of refrige rant in the even t of leaka ge.

Consult the expe rt ab out p revention me asures. If the density o f ref rigerant
exceeds the limit in the event of leakage , lac k of oxygen can occu r, whi ch
can caus e serious accidents .

•

After comp leted insta llation, ch eck that no ref rigerant le aks from the s ystem.

If refrigerant leaks into the room a nd comes into co ntact with a n o ven or
other ho t surface, poisonou s gas is p roduced.

• U se the pre scribed p ipes, flar e nuts an d tools fo r R410A.

Using ex isting parts ( for R22 or R407C) can ca use the unit fail ure and seri­ous acci dents due to burst o f the ref rigerant c ircuit.

• T ighten the flare nu t by torqu e wrench w ith specified me thod.

If the flare nut w ere tightened with excess torque, this may cause bu rst and
refriger ant leakag e after a long peri od.

• D o not open th e operat ion val ves for liquid line and gas lin e until com­pleted r efrigerant piping w ork, air t ightness t est and evacuati on.

If the c ompressor is operated in s tate of o pening operation valves before
complete d connec tion of refrigerant pi ping work, ai r can be sucke d into re­frigeran t circuit, whi ch can cause bust or personal inj ury due to anomal ously
high pre ssure in t he refrig erant.

• D o not put th e drainage pipe di rectly int o drainage channels w here poi­sonous g ases such as sulphid e gas can occur.

Poisonou s gases will flo w into the room through drai nage pipe and s eriously
affect t he user’s health an d safety.

• E nsure t hat no air enters in the refriger ant cir cuit w hen the unit is in­stalled a nd removed.

If a ir en ters in the refr igerant circuit, the pr essure in the refrigerant circuit
becomes too high, which can cause bur st and pe rsonal inj ury.

• D o not proc essing, splice th e po wer c ord, or sh are a socket with other
power plu gs.

This may cause fire or electric shock due to defect ing contact, de fecting in­sulation and over- current e tc.

• T he el ectrical installation must be carried out by the qualifi ed el ectri­cian in accor dance with “th e n orm for electrical work” and “na tional
wiring regulation”, and the s ystem must be conne cted t o the dedicated
circuit.

Power s upply with in sufficien t capaci ty and incorrect fun ction do ne by im­proper w ork can ca use elect ric shocks and fire .

• B e sure to shut off the power before st arting ele ctrical work.

Failure t o shut off the power can cause electric s hocks, uni t failure or incor­rect fun ction of e quipment.

• B e s ure to use the cab les confo rmed to sa fety stan dard and cab le
ampacity for power distribut ion work.

Unconfor mable cables can cause electr ic leak, anomal ous heat production or
fire.

• T his app liance m ust be conne cted to main power suppl y by means of a
circuit br eaker or switc h (fuse:16A ) with a contac t separation of at least
3mm.

• W hen p lugg ing t his ap pli anc e, a p lug conf ormi ng to t he no rm
IEC60884 -1 must be used.

• U se the pre scribed cables for electrical connection, tighten the cables
securely i n terminal block a nd relieve the cabl es correctly to pre vent
overload ing the te rminal bl ocks.

Loose conn ections or ca ble mountin gs can cause a nomalous hea t production
or fire.

• A rrange the w iring in the co ntrol box so t hat it canno t be pushed up
further into the b ox. Instal l the service pa nel correc tly.
